Abstract: A needle magazine (10, 110) for storing a plurality of pen needle assemblies in combination with a plurality of pen needle units is disclosed. The magazines each comprise a first part (11, 111) and a second part (12, 112), each holding a number of pen needle assemblies. The first part (11, 111) and the second part (12, 112) are hinged together by a hinge mechanism (13, 113) such that the pen needle magazine (10, 110) can be folded to be easily carried by a user. The needle magazine (10, 110) also comprises an irreversible locking mechanism (30, 31, 130) such that the needle magazine (10, 110) can be used as a waste bin when discarding the used pen needle assemblies.
